The NFL's Arizona Cardinals went to the Super Bowl last February for the first time in franchise history, mainly on the arm and guts of starting quarterback Kurt Warner. Then, Warner decided to retire, leaving the job to his backup, Matt Leinart.

ESPN.com is reporting the Bills, Raiders and Giants have had discussions about trading for Leinart. The Giants have a definite need for a backup to Eli Manning, since Jim Sorgi is out for the year with a shoulder injury.
